Abstract

Det beskrives en separering av metan fra en blanding (110) med etan og høyere hydrokarboner, spesielt naturgass, ved bruk av en skrubbekolonne (114), der blandingen separeres i en metan-rik topp (116) som delvis kondenseres (122) for å gi refluks til kolonnen (114) og flytende metan-utarmede bunnvæsker (126). Fremgangsmåten forbedres ved å tilveiebringe ytterligere refluks (136) avledet fra en etananriket strøm (130) fra fraksjoneringen (128) av bunnvæsken. Fortrinnsvis er en absorbervæske (140) fra fraksjoneringen (128) også innført i skrubbekolonnen. Dampfraksjonen (120) som er tilbake etter delvis kondensering, kan gjøres flytendegjort (122) for å gi et LNG produkt (124).A separation of methane from a mixture (110) with ethane and higher hydrocarbons, especially natural gas, is described using a scrubber column (114), wherein the mixture is separated into a methane-rich top (116) which is partially condensed (122) to give reflux to the column (114) and liquid methane-depleted bottom fluids (126). The process is improved by providing additional reflux (136) derived from an ethanol-rich stream (130) from the fractionation (128) of the bottom liquid. Preferably, an absorber liquid (140) from the fractionation (128) is also introduced into the scrub column. The vapor fraction (120) remaining after partial condensation can be liquefied (122) to give an LNG product (124).
